Formulated for bonding and sealing applications, Master Bond EP46HT-1AO is widely used in the aerospace, electronic and specialty OEM industries. Unlike most conventional two component epoxies, EP46HT-1AO cures with the addition of heat, which allows it to have a working life exceeding 24 hours. It has a forgiving 100 to 30 mix ratio by weight and bonds well to metals, composites, glass, ceramics and many plastics.

EP46HT-1AO combines thermal conductivity and electrical insulation properties. This dimensionally stable system provides a tensile strength over 7,500 psi, a compressive strength of 26,000 psi and a tensile lap shear strength greater than 1,500 psi at room temperature. EP46HT-1AO also withstands a variety of chemicals including oils, water, acids, bases and solvents.

This unique compound is serviceable over the temperature range of -73°C to +288°C (-100°F to +550°F) and offers a glass transition temperature of 215°C. It should be noted that EP46HT-1AO is relatively exothermic and should not be cured in sections greater than 20-30 thousandths of an inch thick and a bondline thickness is typically 2-7 thousandths of an inch.

This epoxy is available in ½ pint, pint, quart, gallon and 5 gallon container kits. Part A of this system is tan in color and Part B is moderately dark brown. EP46HT-1AO has a 6 month shelf life at ambient temperatures in original, unopened containers.

Specially formulated to optimize bond strength, Master Bond UV15-42C is a UV curable system for bonding, sealing and coating applications. This smooth paste can be applied vertically without sagging. As an optically clear compound, it is often used in the fiber-optic, optical, electronic, aerospace and specialty OEM industries.

This one part system bonds well to a wide variety of substrates including glass, metals, composites, rubbers and most plastics. Adhesion to acrylic and polycarbonates is exceptional. UV15-42C also features a tensile strength of 5,000-6,000 psi and a tensile modulus of 250,000-300,000 psi at room temperature. Its toughness enables it to withstand thermal cycling as well as mechanical shock. UV15-42C is also resistant to chemicals such as water, oils, cleaning agents, acids and bases.

It cures readily in 10-30 seconds upon exposure to a UV light source emitting a 320-365 nm wavelength with an energy output of 20-40 milliwatts/cm². UV15-42C is not oxygen inhibited and will cure in thicknesses up to ¼ inch. This electrically insulative, dimensionally stable system has low shrinkage upon curing.

UV15-42C is serviceable from -65°F to +300°F and is available for use in syringes and cartridges. It can also be purchased in ½ pint, pint and quart containers.

Master Bond EP30-3LO is a two component epoxy system offering optical clarity, high temperature resistance, and NASA low outgassing approval. This combination of properties enables it to be suitable for bonding, sealing, coating and encapsulation applications in the aerospace, electronic, optical and optoelectronic industries.

This epoxy has a glass transition temperature exceeding 175°C. It also withstands many chemicals, particularly water, oils, acids, bases and solvents over the wide service temperature range of -80°F to +450°F. Often selected for potting applications, EP30-3LO features a low viscosity and reliable electrical insulation values.

With a non-critical 100 to 30 mix ratio by weight, this compound cures with the addition of heat ranging from 250-350°F. As it requires oven curing, EP30-3LO has a long pot life of 6-10 hours at room temperature. It bonds well to a wide variety of substrates including metals, glass, composites and many plastics and rubbers.

EP30-3LO delivers a 1 year shelf life in its original, unopened containers. It is available in standard packaging ranging from ½ pint to 5 gallon kits.
